Hereinafter, a cover of a cooking appliance according to a preferred embodiment of the present invention will be described in detail with reference to fig. 1 to 7.

As shown in fig. 1 and 5. The cover body 100 is substantially composed of a surface cover 110, a heat-insulating plate 120, a pressure plate 130, and a packing 140. The insulation board 120 is located below the cover 110, or covers the bottom side of the cover 110. The pressing plate 130 is disposed on the bottom side of the insulation plate 120 such that the insulation plate 120 is at least partially located between the pressing plate 130 and the face cover 110. And the seal 140 is at least partially captured between the platen 130 and the heated platen 120. That is, when the cover body 100 covers the pot body, the insulation plate 120 is located at the bottom side of the top cover 110, the packing 140 is located at the bottom side of the insulation plate 120, and the pressing plate 130 is located at the bottom side of the packing 140.

Both extending from the bottom of the face cover 110 in a direction closer to the pressure plate 130. The reinforcing ribs 111 extend to and abut against the heat insulating plate 120, and apply a force to the heat insulating plate 120 in the direction of the sealing ring 140. Therefore, the sealing ring 140 and the heat insulation plate 120 can form interference fit, and the sealing performance is improved. Preferably, the reinforcing ribs 111 are continuously provided in the circumferential direction. Or ribs 111, are disposed around an opening 131 (described below) of the platen 130. Like this, can be so that the whole circle outer fringe of heated board 120 all with strengthening rib 111 butt, and then make the whole circle homoenergetic of sealing washer 140 and heated board 120 interference fit, further improved the leakproofness.

The pressure plate 130 has an opening 131, and as shown in fig. 3, the main structure of the pressure plate 130 is configured substantially in a ring shape. The opening 131 is located in the middle of the pressure plate 130. In this way, the insulation board 120 can be partially exposed from the opening 131. The top side of the pressure plate 130 is provided with a mating portion 132 that can mate with the snap portion 112 to form a snap. It is easy to understand that the clamping portion 112 and the matching portion 132 can be oppositely disposed, for example, the clamping portion 112 is disposed on the pressing plate 130, and the matching portion 132 is disposed on the face cover 110, as long as the clamping can be achieved. The clip portion 112 and the mating portion 132 may each have a snap-fit structure. Preferably, the plurality of engaging portions 112 are circumferentially spaced apart, and the plurality of engaging portions 132 are circumferentially spaced apart along the periphery of the pressure plate 130. From this, a plurality of snap-fit have improved the firm degree of connection.

Refer to fig. 1, 5, 6 and 7. The sealing ring 140 is disposed along a circumferential direction of the opening 131, and includes a mounting portion 141 and a sealing portion 142, and the sealing portion 142 is connected to the mounting portion 141. Which extends outwardly and inwardly from the mounting portion 141 in a direction away from the insulation board 120 to seal the inner pot of the cooking appliance. And the mounting portion 141 is at least partially sandwiched between the insulation board 120 and the pressing board 130.

Accordingly, the rib 111 abuts against the heat insulating plate 120, and the engagement between the engaging portion 112 and the engaging portion 132 is formed, so that the heat insulating plate 120 and the seal ring 140 can be fixed between the platen 130 and the cover 110.

According to the cover body 100 of the present invention, the connection between the pressing plate 130 and the face cover 110 is achieved by snap-fitting, and the sealing ring 140 is pressed on the pressing plate 130 by the reinforcing rib 111, so that the fixing among the face cover 110, the heat insulation plate 120, the sealing ring 140 and the pressing plate 130 is achieved without perforating the component body, the structural strength is good, the installation process is simple, and the cost is low.

Specifically, refer to fig. 6 and 7. The periphery of the opening 131 of the pressure plate 130 is provided with a flange 133 protruding toward the face cover 110. The mounting portion 141 is configured as a groove shape with its mouth facing away from the face cover 110, and the mounting portion 141 is fitted onto the flange 133.

Refer to fig. 4, 6 and 7. The heat insulating plate 120 includes a body portion 121 and a connecting portion 122. Wherein the connecting portion 122 is located at the periphery of the body portion 121. The connecting portion 122 is used for connecting with the mounting portion 141. Specifically, it is connected to a side of the mounting portion 141 facing the face cover 110. It is easily understood that the reinforcing rib 111 abuts on the connection portion 122, so that the force applied thereto can be transmitted to the heat insulating plate 120 and the sealing ring 140 at the same time. The connecting portion 122 is preferably configured as a groove shape with its opening facing away from the surface cover 110, and is fitted to the mounting portion 141.

The sealing ring 140 further includes an additional sealing portion 143, and the additional sealing portion 143 is provided at a connection of the mounting portion 141 and the sealing portion 142. Which extends circumferentially towards the middle of the seal ring 140. Alternatively, the additional seal 143 extends in a horizontal direction while contracting inward. After the mounting, the additional sealing part 143 is positioned at the bottom side of the body part 121 of the insulation board 120, thereby realizing multiple sealing to the insulation board 120.
